Anfibios y reptiles del departamento de Ica con comentarios sobre su distribución

En este trabajo se presenta el listado actualizado de anfibios y reptiles de Ica. Las especies son comentadas, acompañadas de mapas de distribución y claves de identificación para reptiles y anfibios. Se recopiló información de registros en colecciones científicas, artículos científicos, informes de agencias gubernamentales de vida silvestre y bases de datos taxonómicas especializadas. Adicionalmente, entre los años 2019 y 2020 se realizaron evaluaciones de campo en zonas con vacíos de información. Se encontraron un total de 22 especies (anfibios 3 y reptiles 19). Los nuevos registros de reptiles para Ica incluyen la lagartija Liolaemus evaristoi y la serpiente Incaspis tachymenoides en la provincia de Chincha a 4200 y 3200 m de altitud respectivamente, la lagartija Stenocercus ornatissimus y la serpiente ciega Epictia tesselata en la provincia de Pisco a 3500 y 2800 m respectivamente. Los nuevos registros de anfibios incluyen a Pleurodema marmoratum en la provincia de Chincha (3900 m) y Telmatobius rimac en las provincias de Chincha y Palpa a 3900 y 2350 m respectivamente. La mayor riqueza y endemismos locales se encontraron en el desierto costero, mientras que, las ampliaciones de distribución y endemismos regionales se registraron en la vertiente occidental de los Andes. También, se observa que las familias Leptotyphlopidae y Viperidae, y los géneros Dicrodon, Stenocercus y Oxyrophus terminan su distribución en la vertiente occidental y la zona costera de los departamentos de Ica y Arequipa sin representantes en el extremo sur del Perú y Chile.

This paper presents the updated list of amphibians and reptiles of Ica. Species are commented, accompanied by distribution maps and identification keys for reptiles and amphibians. Information was collected from scientific collections, scientific articles, governmental wildlife agency reports, and specialized taxonomic database. Additionally, between 2019 and 2020, field surveys were carried out in areas with information gaps. A total of 22 species were found (amphibians 3 and reptiles 19). The new records of reptiles include the Liolaemus evaristoi lizard and the Incaspis tachymenoides snake from Chincha province at 4200 and 3200 m altitude respectively, the Stenocercus ornatissimus lizard and the blind snake Epictia tesselata from Pisco province at 3500 and 2800 m respectively. New amphibian records include Pleurodema marmoratum in Chincha province (3900 m) and Telmatobius rimac in Chincha and Palpa provinces at 3900 and 2350 m respectively. The greatest richness and local endemism were found in the coastal desert, while the expansion of distribution and regional endemism were recorded on the western slope of the Andes. Also, it is observed that the families Leptotyphlopidae and Viperidae, and the genera Dicrodon, Stenocercus and Oxyrophus are finishing their distribution in the western slope and the coastal zone of the departments of Ica and Arequipa without representatives in the extreme south of Peru and Chile.

Registros de Collembola (Arthropoda, Hexapoda) no Estado do Rio Grande do Norte, Brasil / Records of Collembolans (Arthropoda, Hexapoda) from Rio Grande do Norte State, Brazil

O estado de conhecimento sobre Collembola no Brasil é deficitário, sendo a maior parte dos biomas pobremente amostrados. Este trabalho tem por objetivo fornecer uma lista de espécies de colêmbolos para o Estado do Rio Grande do Norte. As coletas foram realizadas nos municípios de Extremoz, Natal, Parnamirim e Serra Negra do Norte, por meio da utilização de armadilhas de queda, armadilha luminosa e coleta manual diretamente do substrato. Foram registradas 16 espécies, distribuídas em 12 gêneros e sete famílias. A família com maior riqueza de espécies foi Entomobryidae, com sete espécies. O gênero com maior número de espécies foi Seira, com quatro. As duas únicas espécies registradas na Caatinga também foram observadas nas áreas de Mata Atlântica. Por outro lado, tais espécies são novas para a ciência, o que sugere a urgência de um inventário na Caatinga, domínio ainda subestimado. Foram encontradas cinco espécies novas de colêmbolos no Estado.

The state of knowledge of collembolans in Brazil is deficient and most biomes are poorly sampled. This paper provides a list of species of Collembola from Rio Grande do Norte State. The samplings were carried out in the municipalities of Extremoz, Natal, Parnamirim and Serra Negra do Norte, by using pitfall traps, light traps and direct collections. Sixteen species of springtails were recorded, distributed in 12 genera and seven families. The family with the highest diversity was Entomobryidae, with seven species. The most speciose genus was Seira, with four species. Only two species were recorded in Caatinga and they both were also reported to areas of Brazilian Atlantic Forest. However, these species are new to science, which indicates the urgency of a full inventory in Caatinga, an underestimated domain. Five new species of Collembola were found in the State.

Sand flies of Nicaragua: a checklist and reports of new collections

Sand flies within the genus Lutzomyia serve as the vectors for all species of the protozoan parasite Leishmania in the New World. In this paper, we present a summary of the 29 species of Lutzomyia and one of Brumptomyia previously reported for Nicaragua and report results of our recent collections of 565 sand flies at eight localities in the country from 2001-2006. Lutzomyia longipalpis was the predominant species collected within the Pacific plains region of western Nicaragua, while Lutzomyia cruciata or Lutzomyia barrettoi majuscula were the species most frequently collected in the central highlands and Atlantic plains regions. The collection of Lutzomyia durani (Vargas & Nájera) at San Jacinto in July 2001 is a new record for Nicaragua. Leishmaniasis is endemic to Nicaragua and occurs in three forms: cutaneous, mucocutaneous and visceral leishmaniasis. Cutaneous infections are the most prevalent type of leishmaniasis in Nicaragua and they occur in two different clinical manifestations, typical cutaneous leishmaniasis and atypical cutaneous leishmaniasis, depending on the species of the infecting Leishmania parasite. The distribution of sand flies collected during this study in relation to the geographic distribution of clinical forms of leishmaniasis in the country is also discussed.

Registros da fauna de Collembola (Arthropoda, Hexapoda) no Estado da Paraíba, Brasil / Records of collembolan fauna (Arthropoda, Hexapoda) in Paraíba State, Brazil

No presente trabalho são listadas as espécies de Collembola encontradas no Estado da Paraíba, Região Nordeste do Brasil. Os espécimes foram coletados em seis municípios: João Pessoa, Cabedelo, Mataraca, Bananeiras, Cacimba de Dentro e Araruna. Os espécimens foram coletados através do processamento de material em funis de Berlese-Tullgren, armadilhas do tipo pitfall e aspiradores entomológicos. Em seguida foram montados entre lâminas e lamínulas de vidro para identificação sob microscópio. Foram identificadas 54 espécies de colêmbolos, distribuídas em 25 gêneros, em 13 famílias. Entomobryidae foi a mais diversa, com 22 espécies e Seira foi o gênero mais diverso, com 15 espécies. A maior parte das espécies foi encontrada em remanescentes de Mata Atlântica e Mata de Restinga. Foram encontradas 20 novas espécies de colêmbolos e serão descritas posteriormente. Os dados aqui apresentados indicam que a Paraíba é um hotspot de diversidade para o gênero Seira.

In this paper the species found in Paraíba State, northeatern Brazil are listed. The specimens were collected in six municipalities: João Pessoa, Cabedelo, Mataraca, Bananeiras, Cacimba de Dentro and Araruna. The specimens were collected using Berlese-Tullgren funnels, pitfall traps and entomological aspirators. After that they were mounted in glass slides for identification under microscope. It was found 54 species of collembolans, distributed in 25 genera, of 13 families. Entomobryidae was the most diverse family, with 22 species and Seira was the prevailing genus, with 15 species. Most species were found in fragments of Mata Atlântica and Mata de Restinga. Twenty new species were found and will be describe later. The data indicate that Paraíba is possibly a hotspot of diversity for the genus Seira.
